CLAItENCE CULLEN CRISPEN, OF HARRISBURG, PENNSYLVANIA.

LUBBICATOR.

Application filed February 26, 1921-.

To all whom, it may concern:

Be it known that I, CLARENCE CULLEN CRIsrnN, a citizen of the United States, and a resident of Harrisburg, in the county of Dauphin and State of Pennsylvania, have invented certain new and useful Improve ments in Lubricators, of which the followin is a specification.

l y invention relates to lubricators particularly adapted, although not necessarily, for the lubrication of chassis for automobiles, locomotives and the like.

The purpose of my invention is the provision of a lubricator in which wicks are employed in conjunction with an oil reservoir or container in such manner as. to. effeet the automatic and uniform distribution of the oil to elements to be lubricated that are disposed remote from the container, my invention being especially adapted for the lubrication of parts which require that they be steadily fed with oil in very small quantities, such as the steering bolts, spring bolts, and other similar parts of a vehicle chassis.

I will describe one form of lubricator embodying my invention and will then point out the novel features thereof in claims.

In the accompanying drawings:

Figure 1 is a View showing in vertical section one form of lubricator embodying my invention. a

Figure 1 is a fragmentary perspective view showing in detail the means for latching the plunger in elevated position.

Figure 2 is a detail view showing the inner side of one of the side members comprised in the lubricator shown in Figure 1.

Figure 4 is a fragmentary transverse sectional view taken on the line 4-4 of Figure 3 and looking in the direction of the arrows.

Figure 5 is an auxiliary oil cup adapted for use in conjunction with the oil jlubri' cator. j

Similar reference characters referto similar parts in each of the several views.

Referring specifically to the drawings and particularly to Figure 1, the lubricator in its present embodiment comprises a container including a body B having an oil chamber comprising an upper portion 15 and a lower portion 16. Two sides of that part of the body forming the upper portion of the oil chamber are formed with a bead- Specification of Letters Patent.

ing 17 to which is adapted to be bolted a cover plate 18 and side members designated generally at M. The cover-plate 18 is provided with a screw plug 19 to permit the introduction of oil into the container, while the lower wall of the lower portion 16 is likewise provided with a screw plug 20 to permit of the draining of oil and sediment from the container when cleaning thelubricator.

Each side member M comprises a rectangular body portion 21 which in applied position completely closes the corresponding side'of the upper portion 15 of the oil chamber. The body portion 21 is formed with a plurality of vertically extending ducts 22 having at their upper ends branch ducts 22 which effect communication between the ducts 22 and the upper portion of the oil chamber. The lower ends of the ducts 22 are in communication with distributing pipes 23, such pipes extending to the parts to be lubricated. The inner side of each side member M is provided with a plurality of hooks 24 to which are secured the'inner ends of wicks 25. As shown in Figure 1, these wicks 25 extend upwardly from the hooks 24 and pass through the ducts 22 and 22 with their opposite ends terminating adjacent the upper ends of the distributing pipes 23.

Working within the body B of the container is a plunger P of rectangular formation provided with a rod 26 which is slidably fitted in a suitable opening formed in the cover} plate 18. shown) is adapted to be employed for moving the plunger from the lower portion 16 of the oil chamber to the upper portion 15 or vice versa'and for maintaining the plunger in the uppermost position. This plunger is designed for the purpose of displacing the oil from the upper portion of the oil chamber to the lower portion of the oil chamber, or vice versa, and to thereby cause such oil to move into or out of contact with the several wicks 25. To prevent splashingof the oil upon the wicks and into the ducts 22, baffie plates 27 are provided, which as Suitable means (not shown in Figure 1 are spaced from the inner I sides of the side members M to provide a restricted channel in which the oil from the container is adapted to be deposited when the plunger is in the upper portion of the oil chamber. Entrance to either of these channels is obtained through a plurality of openings 28 adjacent the lower edge of the baffle plate, while free circulation of air within the body of oil is permitted by virtue of openings 29 along the upper edge of the battle plate, all as clearly shown in Figure 3. The plunger is adapted to be secured in its uppermost or elevated position by means of a lat-ch bar 35 pivoted at 36 on the cover plate 18 and having a beveled end which is adapted to repose in a notch 26 formed in the rod 26, all as clearly shown in Figure l In the operation of the lubricator, the oil chamber is partly fed with oil, and with the plunger positioned within the lower portion of the oil chamber as shown in Figure 1, the oil is displaced to the upper portion of the oil chamber where it passes into the channels between the side members and the baflie plates. The wicks 25 being disposed within these channels, it is obvious that by virtue of the capillary attractive property of the wicks, such oil will be fed into the ducts 22, and from these ducts into the dis tributing pipes 23. I consider the employ ment of wicks in this capacity a very important feature of my invention because by the use of wicks, a constant and uniform distribution of the oil to the distributing pipes is automatically effected, and that by varying the character of the material of which the wicks are formed and the cross sectional area thereof, a varied feeding of the oil can be effected so that should it be desired to feed a greater quantity orless quan tity of oil to any particular distributing pipe, it can be accomplished b merely varying the character of the wick.

When it is desired to disconi'nue the feeding of oil to the distributing pipes, the body of oil within the container can be moved out of contact with the wicks by lifting the plunger to the upper portion of the oil chamber and securing the same by means of the latch bar 35, thereby allowing the body of oil to move into the lower portion of the oil chamber and thus out of contact with the wicks.

Referring now to Figure 5, I have here shown one form of oil cup which is adapted to be used in conjunction with the lubricator previously described for effecting the distribution of oil from any one of the distributing pipes'23 to a plurality of remote points. The cup is designatedat Candis adapted to be closed by a screw plug 30. The sides of the cup are formed with a plurality of radially extending ducts 31 one of which is connected to one of the distributing pipes 23, while the remaining ducts are connected to distributing pipes 32. Wicks 25 are arranged within the cup with one end extending into the ducts 31 which are in communication with the distributing pipes 32.

From the foregoing arrangement, it will be seen that oil is supplied to the cup C through the pipe 23, and. such oil is fed from the cup to the distributing pipes 32 through the wicks 25 the ducts 31 being arranged adjacent the upper end of the cup so that only the lower portion of the wicks is submerged within the oil.

Although I have herein shown and described only one form of lubricator and one form of oil cup embodying my invention, it is to be understood that various'changes and modifications may be made herein without departing from the spirit of the invention and the spirit and scope of the appended claims.

What I claim is:

A lubricator comprising, a container, oil distributing pipes in communication with the container, wicks associated with the container and pipes in a manner to feed oil from the container to the distributing pipes by means of-capillary attraction, andJa ,plunger movable within the container to occupy one position in which the oil in the container is in contact with the wicks and another position in which the oil is out of contact with the wicks.

2. A lubricator comprising, an oil container formed to provide an upper oil chamber and a lower oil chamber, distributing ducts in communication with the upper chamber, wicks extending from the upper chamber into said ducts, anda plunger operating to move the oil in the container from the upper chamber to the lower chamber or vice versa whereby, the oil will be moved into or out of contact with the wicks.
